Abstract

The optionally 2-substituted 5-chloroimidazoles of the general formula <IMAGE> are novel intermediates for the preparation of antihypertensive pharmaceuticals (vasodepressants) or of herbicidally active compounds. There are described a process for the preparation of these intermediates and a novel process for the further reaction of optionally 2-substituted 5-chloroimidazoles of the general formula I in which R<1> is hydrogen to give the optionally 2-substituted 5-chloroimidazole-4-carbaldehydes of the general formula <IMAGE>
